Method Detail

SaveFileFormat

public static void SaveFileFormat(float[][][] imageSamples,
                                  java.lang.String imageFile,
                                  int format)
                           throws WarningException

Saves image samples using specified format using JAI. This function uses byte type to save image (because is the only allowed by JAI libraries) and it can manage only images with 1 or 3 components. File extension is added automatically depending on the format.

Parameters:

imageSamples - a 3D float array that contains image samples

imageFile - file name where raw data will be stored

format - format type to save image. The value indicates the following:

• 0- PNM (pgm or ppm)
• 1- TIFF
• 2- PNG
• 3- JPEG (not recommended because it degenerates image)
• 4- BMP (not recommended because it is not standard)

Throws:

WarningException - when the file cannot be saved (incorrect number of components, file format unrecognized, etc.)

SaveFileRaw

public static void SaveFileRaw(float[][][] imageSamples,
                               java.lang.String imageFile,
                               int sampleType,
                               int byteOrder)
                        throws WarningException

Saves image samples in raw data.

Parameters:

imageSamples - a 3D float array that contains image samples

imageFile - file name where raw data will be stored

sampleType - an integer representing the class of image samples type. Samples types can be:

• 0- boolean
• 1- byte
• 2- char
• 3- short
• 4- int
• 5- long
• 6- float
• 7- double

byteOrder - 0 if BIG_ENDIAN, 1 if LITTLE_ENDIAN

Throws:

WarningException - when the file cannot be saved (incorrect number of components, file format unrecognized, etc.)

SaveFileByExtension

public static void SaveFileByExtension(float[][][] imageSamples,
                                       java.lang.String imageFile,
                                       int[] imageGeometry)
                                throws WarningException,
                                       ParameterException

Saves image samples in the format given by the extension.

Parameters:

imageSamples - a 3D float array that contains image samples

imageFile - file name where raw data will be stored

imageGeometry - a 1D integer array that contains the format when the data is stored in raw data

Throws:

WarningException - when the file cannot be saved (incorrect number of components, file format unrecognized, etc.)

ParamterException - when saving with raw mode and the imageGeometry parameter has some problems

ParameterException

getFormat

public static int getFormat(java.lang.String imageFile)
                     throws WarningException

Gets the extension, if any, of the image to be saved.

Parameters:

imageFile - contains the name of the image to be saved

Returns:

an integer that indicated containing the format

Throws:

WarningException - when the file has no extension
